  Inductive Touch Buttons for HMIs
  PDF, 315 Kb, 档案已发布: Jan 9, 2017
  Consumer electronic device designs need to beattractive and reliable to be successful. However, mostdevices still rely on mechanical buttons which oftenemploy moving parts, gaskets, and cutouts leading tolong term reliability issues, increased costs, andinferior immunity to environmental factors. Inductivetouch buttons on the other hand enable aestheticallyattractive, gasket less, an

  Inductive Touch - Configuring LDC2114 Touch-Button Sensitivity
  PDF, 771 Kb, 档案已发布: Mar 16, 2017
  Erroneous or unintended button presses can result in a frustrating user experience in a human machine interface (HMI). Capacitive touch buttons trigger anytime a grounded object is brought close to the button; this can often cause false or erroneous button presses. One advantage mechanical buttons have over capacitive touch buttons is that a certain amount of force must be applied on the buttons f
